Description:
Tulsa 4-4-4-4 Aluminum wire is an underground electricity cable that also works as a service entrance cable and cabling for underground secondary circuits. The four conductors of this cable are 4 AWG sizes. This makes it a 3 phase cable and the 4th wire is a neutral wire has yellow stripes. The cable is a medium duty service because of its 90°C temperature rating and 600 volts. It has an ampacity of 120 amps when buried and 85 amps when used in ducts.

Applications:
#4 Tulsa Quadruplex URD Cable is used for underground power supply systems in residential zones. The cable can used for direct burial or can be installed in conduits or ducts which channel the cable to a given direction. Furthermore it can also be used in wet and dry locations.

Conductors:
The conductors are made of aluminum alloy 1350-H19. The conductors are each stranded for flexibility.

Insulation:
It is made of cross-linked polyethylene. It can withstand high temperatures of 90°C.

Features:
• It has sequential footage markings
• Heat and moisture resistant
• Approved for use by international standards
• Temperatures of 90°C

Standards:
• Secondary UD quadruplex conductor 600V cable meets or exceeds the following ASTM specifications.
• B-230 Aluminum Wire, 1350-H19 for Electrical Purposes.
